What kind of robotics parts can we make?

Robotika produces a wide range of CNC-machined components for the robotics industry, such as joint housings, gear brackets, actuator bases, end-effector fingers, cooling plates, and sensor enclosures. For load-bearing and structural parts, we typically machine aluminum alloys to ensure high strength while keeping weight low, and stainless steel for wear resistance in high-friction joints. Copper and brass are applied in conductive or heat-dissipating components like busbars and thermal plates, while engineering plastics such as PEEK and nylon are chosen for lightweight insulation, low noise, and smooth motion in sliding or guiding parts. To meet the functional and aesthetic demands of robotic systems, we provide finishes including anodizing for corrosion protection, bead blasting and brushing for improved surface texture, hard coating for wear resistance, and powder coating for durability.
